Targeted SMS campaigns, although they are quite expensive, yield good results. I don't know where they get their database, but thanks to it, I attracted quite a few interested clients. There is one downside: they charge extra for each target. For example, I specified the city – that added 20 kopecks, age – another 10 kopecks, and so on. In my case, income and interests were important, which made the campaign quite costly, but it ultimately paid off. Their minimum order amount is 5,000 rubles. I invested 20,000, and the result was excellent. The impressions started coming in about a day later, and I used my own text. They offered to create a sales text, but my version worked just fine. In the end, they provided me with a report on the campaign that accurately reflected reality.
